Everything that is new or uncommon raises a pleasure in the imagination, because it fills the soul with an agreeable surprise, gratifies its curiosity, and gives it an idea of which it was not before possessed.

An understanding of the natural world and what's in it is a source of not only a great curiosity but great fulfillment.

David Attenborough

Curiosity in children, is but an appetite for knowledge. One great reason why children abandon themselves wholly to silly pursuits and trifle away their time insipidly is, because they find their curiosity balked, and their inquiries neglected.

Frivolous curiosity about trifles, and laborious attentions to little objects which neither require nor deserve a moment's thought, lower a man, who from thence is thought, and not unjustly, incapable of greater matters.

Philip Dormer Stanhope Chesterfield

Leisure and curiosity might soon make great advances in useful knowledge, were they not diverted by minute emulation and laborious trifles.

The patient. The pine tree seems to listen, the fir tree to wait: and both without impatience: - they give no thought to the little people beneath them devoured by their impatience and their curiosity.
